WINDING APPARATUS BACKGROUND OF THE INVENTION The present invention relates to a new and improved construction of winding apparatus comprising a driven wound thread package-support member, a selfthreading traversing thread guide for guiding the thread within the traversing width of a cross-wound package, and a movable auxiliary thread guide for guiding the thread within a waste winding zone on the thread package-support member.

Winding devices of the aforementioned type are already known to the art on draw-winding machines and on spin-draw-winding machines, and by means of such winding devices it is possible to wind on the same thread package-support member, apart from the wound thread package, also a so-called knotting reserve winding or waste winding. As a general rule the knotting reserveor waste windings are wound at the beginning of the winding process, i.e. prior to the start of the actual winding of the thread package, onto an end portion of the thread package-support member, for instance a bobbin tube or sleeve, in close vicinity to the zone of the actual package winding region. I

The present invention is an extension of the arrangement proposed heretofore and described in Swiss Pat. No. 459,839 wherein externally of the working zone of the traversing thread guide and between such traversing thread guide and a stationary thread guide arranged upstream of the traversing thread guide there is mounted at the machine frame an adjustable auxiliary thread guide which can be adjusted while the machine is at standstill and which remains fixed during machine operation. The adjustable auxiliary thread guide serves to wind reserve windings at the beginning of the wind ing process, that is before winding of the cross-wound package is started.

According to other prior art arrangements wherein for the purpose of guiding the thread in a waste winding zone there is provided a lever which is pivotable in a plane parallel to the axis of the wound thread package and containing a thread guide notch, as disclosed for instance in German Petty Pat. No. 1,913,283 and US. Pat. No. 3,276,704, or according to the arrangement described in British Pat. No. 953,221 wherein a rotatable member containing a thread guide notch is provided, the rotatable member having a fixed axis arranged at right angles with respect to the bobbin axis, the duration of the time for winding the reserve winding can be adjusted, yet these adjustments can be undertaken only during such time as the machine is at standstill, not when the machine is in operation.

SUMMARY OF THE INVENTION Hence it is a primary object of the present invention to provide an improved construction of winding apparatus of the aforementioned general type which is not associated with the limitations of theprior art constructions. i

Another and more specific object of the present invention aims at eliminating the disadvantages of the winding devices of the prior art discussed above.

Yet a further significant object of i the present invention relates to an improved construction of winding apparatus provided with an auxiliary thread guide for guiding the thread within a waste winding zone of a thread package-support member, and wherein the auxiliary thread guide is supported such that it can be adjusted during operation of the winding apparatus.

Now in order to implement these and still further objects of the invention, which will become more readily apparent as the description proceeds, the winding apparatus of this development contemplates adjustably arranging the auxiliary thread guide so as to be movable substantially parallel to and transversely with respect to the axis of the thread package-support member or substantially parallel to and transversely to the traversing direction of the traversing thread guide, the auxiliary thread guide being selectively movable in the one and/or other direction.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood and objects other than those set forth above, will become apparent when consideration is given to the following detailed description thereof. Such description makes reference tive variant constructions of the winding apparatus depicted in FIGS. 1 to 4 inclusive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Describing now the drawings, the exemplary embodiment of winding apparatus depicted in FIGS. 1 to 4 will be seen to comprise a thread package-support member 1, for example a cylindrical bobbin tube or sleeve. which is detachably mounted upon a rotatably supported bobbin chuck which has not been particularly shown in the drawing. The thread package-support member 1 can be driven in any suitable manner, for instance by means of a friction drive drum 1'. A thread 2 or the like supplied by any suitable delivery arrange ment and therefore not particularly depicted in the drawing is guided via a stationary thread guide 3 mounted at the machine frame 9 and a self-threading traversing thread guide 4 which traverses to-and-fro along the thread package-support member 1, in order to wind the thread 2 onto the package support member 1. This traversing thread guide 4 which traverses toand-fro between two extreme positions serves to determine the traversing thread triangle indicated with dashdotted lines in FIG. 3 and the actual winding region, that is to say, the winding stroke or thread traversing width L of a cross-wound package 5 which is produced in this manner.

I Now for the purpose of forming waste windings 6 and adjacent reserve guide 4 6' on the thread packagesupport member 1 at the beginning of the winding operation, that is to say, before the actual cross-wound package 5 is started, there is provided according to the invention an auxiliary thread guide 7. This auxiliary thread guide 7 is pivotably adjustably arranged between the stationary thread guide 3 and the thread package-support member 1 directly upstream of the traversing thread guide 4 with respect to the thread transport direction indicated by the non-referenced arrows appearing at the upper portion of FIG. 1. The auxiliary thread guide 7 is mounted to be adjustable at least substantially parallel to as well as also traversely to the axis A of the thread package-support member I or the direction of the traversing movement of the traversing thread guide 4 respectively.

Continuing, it is to be recognized that the auxiliary thread guide 7 contains a thread guide edge 8 extending in a plane substantially perpendicular to the axis A of the thread package-support member 1 for guiding the thread 2 at the beginning of the winding operation or process, the auxiliary thread guide thus extending in the radial plane defined by the thread guide edge. ln the embodiment depicted in FIGS. 1 through 4 the auxiliary thread guide 7 is formed by a two-dimensional polygonal plate member extending in the direction of the axis A of the package support member 1 over at least substantially the full width of the winding zone and is connected to a guide rod 9 which extends essentially parallel to the axis A of the thread packagesupport member 1. The guide rod 9 is supported in any suitable manner at the machine frame 9' so as to be displaceable both in axial direction as well as also rotatably mounted about its own lengthwise extending axis and therefore can selectively displace the auxiliary thread guide 7 pivotably about the axis of the guide rod 9 transversely with respect to the direction of the axis A of the package support member 1 or with respect to the direction of movement or traversing motion of the traversing thread guide 4, and such auxiliary thread guide can also be moved parallel to the aforementioned axis A of the package support member or the direction of the traversing motion of the traversing thread guide 4 respectively. The thread guide edge 8 which extends approximately radially towards the outside from the guide rod 9, transforms at its outer end into a thread shifting or run-off edge 8'. This thread shifting edge 8 forms an extension of the thread guide edge 8 and is inclined towards the radial plane defined by the center of the traversing zone perpendicular to the axis of the thread package-support member 1. and further, extends at an angle towards the outside, this thread shifting edge 8' being used for the formation of the knottingor reserve winding 6'. The outer end of the thread shifting edge 8' is determined by the termination of the reserve windings which in most cases end immediately before the point where the cross-wound package is started, that is to say, normally in close vicinity to the traversing width L and coincides with the intersection of the thread guide edge 8' and the radial plane con taining the end of the reserve winding 6'.

Now from the region of the outer end of the thread shifting edge 8' there extends a thread catching edge at an inclination towards the guide rod 9 to a point located about at the center of the traversing zone. At this location a further thread catching edge ll extends in the direction of the other end of the auxiliary thread guide 7 opposite to the thread guide edge 8, the further thread catching edge 11 extending in a manner such that the distance to the guide rod 9 continuously increases. ln this way there is formed a substantially V- shaped slot by the intersecting thread catch edges 10 and 11. The inclination of these thread catching edges 10 and 11 in the direction of the guide rod 9 is chosen such that the aforesaid thread catching edges meet at about the center of the traversing zone 1 l and enclose a preferably obtuse angle [3. These thread catching edges 10 and 11 partially enclose or surround the thread 2 when the thread catching edges 10 and 11 assume the position depicted in H0. 4. The thread 2, under the influence of the thread tension, glides towards the center of the traversing zone, i.e. towards the apex or point where the two thread catching edges 10 and 1] meet. By axially traversing the auxiliary thread guide 7 to-and-fro in its catching position over a smaller zone than the regular traversing zone L there can be formed a second waste bunch 12 extending over the traversing width of the auxiliary thread guide 7 while the machine is slowed down to standstill, e.g. upon completion of a cross-wound package 5 or if an eventual disturbance in operation occurs.

in the case of draw-winding machines and spin-drawwinding machines containing a large number of winding positions it is advantageous to provide centrally controlled actuating means for adjusting the movable auxiliary thread guide element. For this purpose the guide rod 9 of the auxiliary thread guide 7, in the exemplary embodiment depicted in H65. 1 to 4, is linked via a lever 13 to a piston rod 14 of an adjustment device 15 which can be actuated by a pressurized medium for rotating the guide rod 9 and thus pivoting the auxiliary thread guide 7. For this purpose the adjusting or adjustment device 15 can be constituted by a pressure medium cylinder which is connected with a central control unit 18 via two conduits or ducts l6 and 17 for the pressurized fluid medium in order to be able to pivot the auxiliary thread guide 7 in the desired sense or direction of rotation. To permit individual manual adjustment of the auxiliary thread guides 7 arranged on the guide rod 9 of a machine at right angles or transversely with respect to the axis of the associated thread package-support member 1 or the direction of the traversing motion of the thread traversing guide 4 the auxiliary thread guides 7 are each suitably connected with the guide rod 9 via a slip clutch 7'. The slip clutch 7' may consist of a bolt inserted into guide rod 9, the bolt extending through a slit provided at the auxiliary thread guide 7 and guiding the latter in such manner that a predetermined friction prevails between the bolt and the slit. Thus, as the guide rod 9 is rotated the bolt embedded therein slides within the slit of the auxiliary thread guide 7 until it impacts against one or the other of the end walls of the slit so as to selectively upwardly and downwardly pivot the auxiliary thread guide 7. The slip clutch 7' is but an example of mechanism suitable for this purpose and the invention is not concerned with any specific construction of slip clutch as other equivalent devices can be readily conceived to carry out the intended purpose of selectively pivoting the auxiliary thread guide. Owing to this arrangement the thread 2 can be threaded-up at individual winding positions while the machine is running without influencing neighboring winding positions. In order to axially shift the guide rod 9 and the auxiliary thread guides 7 mounted thereon this guide rod 9 is operatively connected with another piston rod 19 of a further adjustment device 20, as best seen by referring to FIG. 4, this adjustment device 20 also being activated by a pressure medium and connected via two conduits or ducts 21 and 22 preferably to the same control mechanism or unit 18.

The operation of the winding apparatus of the present invention has been depicted in FIGS. 1 to 4 wherein there is also characterized the four positions of the auxiliary thread guide 7. In FIG. 1 the auxiliary thread guide 7 is depicted in a first working position or a starting position, its thread guide edge 8 being pivoted at right angles or transversely with respect to the direction of the axis of the thread package-support member 1 into the thread guide plane defined by the thread triangle. In this position the threads 2 are secured in known manner at each of the associated thread packagesupport members 1 while the machine is at standstill. Thereupon the machine is started and for control purposes it is initially run at the so-called crawling speed," that is to say, slowly at a fraction of the normal operating speed. Thereafter the drive motor is gently speeded up close to the rated operational speed and then is switched to the normal operating speed. During this time the thread 2 slides on the thread guide edge 8 of the associated auxiliary thread guide 7 and is wound in the form of a small waste bunch 6 at the outer rim of the thread package-support member I. In this process step the thread of impaired quality produced during the start-up and speed-up to the normal speed of the machine, is separately wound. As the rated oper' ating speed of the machine is reached the auxiliary thread guide 7 is pivoted from the position shown in FIG. 2 into the position shown in FIG. 3. During this pivoting motion the thread 2 slides along the thread shifting edge 8' to the outer end thereof, whereby there is formed the thread reserve windings 6 which appear at the start of the winding operation. The pivoting speed of the auxiliary thread guide 7 is chosen as a function of the desired number of reserve windings or the desired length of the reserve thread and is appropriately adjustable. The thread 2 now slides over the outer end of the thread shifting edge 8 into the operable zone of the self-threading traversing thread guide 4, where the thread 2 is engaged thereby for the purpose of building the cross-wound package 5. Upon completion of the cross-wound package 5, or also in the case of premature interruption of the winding process, eg due to a disturbance, the machine is stopped and at the same time the auxiliary thread guide 7 is again pivoted into the starting position shown in FIG. 4, which position is basically identical with the position shown in FIG. 1 with the difference, however, that the thread 2 in this case is caught by the two thread catching edges 10 and 11 and is lifted-off the traversing thread guide 4. As the thread guide rod 9 with the auxiliary thread guide 7 mounted thereon is reciprocated to-and-fro there is formed on the cross-wound package 5 a tapewidth waste bunch 12. In this process step the thread of impaired quality produced while the machine is slowing down to standstill due to the changed operating conditions is distinctly marked.

From the above-described function there is derived a further specific characteristic feature of the thread shifting edge 8, namely that the thread shifting edge 8' is to be arranged under at least an approximately right angle with respect to the resulting tension 1 combined from the partial tensions t, and in the incoming and outgoing portion of the thread passing over the thread shifting edge 8'. The thread shifting edge 8' can be configured as a straight line or according to the configuration of the thread tension diagram of the thread tensions t, and resulting from the arrangement and the dimensions can also deviate from a straight line and thus for instance can be slightly curved.

According to the variant embodiment depicted in FIG. 5 which can be used in the general arrangement of winding apparatus shown in FIG. 2 the first thread reserve Winding 6' also can be formed by shifting the auxiliary thread guide 7 by moving the guide rod 9 parallel to the axis of the package support member 1 by means of an adjustment device like the adjustment device 20 of FIG. 1 but not shown in FIG. 5 to simplify the illustration and at the same time by pivoting the auxiliary thread guide 7 into the position indicated by broken or phantom lines by means of the adjustment device 15. In this case the auxiliary thread guide 7, instead of a thread guide edge 8 and a thread shifting edge 8', contains a thread guide edge 23 which also extends at least approximately radially towards the outside from the location of the guide rod 9. This thread guide edge 23 furthermore also substantially extends at least approximately to the outer end of the auxiliary thread guide 7 in the same radial plane and at its outermost end can merge via a preferably slightly rounded edge portion 23' into the thread catching edge 10, slid ing of the thread 2 off of the thread guiding edge 23 being facilitated up to this moment. Hence, it will be appreciated that the embodiment of FIG. 5 only differs from the embodiment of FIGS. 1 to 4 in the abovediscussed modification of the construction of the auxiliary thread guide, but otherwise the manner of forming the waste windings. reserve windings and second waste bunch is the same as explained heretofore with respect to the embodiment of FIGS. 1 to 4.

According to a further embodiment as depicted in FIG. 6 the auxiliary thread guide 7 need not necessarily be mounted upon a rotatably supported guide rod 9, rather can be equally satisfactorily arranged to be movable parallel to the axis of the package support member I or the direction of the traversing motion of the traversing thread guide 4 respectively and can also be coupled with the adjustment device or mechanism 20 in the manner depicted in FIG. 4. To permit removal of the auxiliary thread guide 7 from the traversing thread guide plane for the build-up of the cross-wound package, as indicated in FIG. 6, the auxiliary thread guide 7 is supported movably at right angles with respect to the axis A of the thread package-support member 1 in guide 25 which are piston rods of cylinders connected with the actuating or adjustment device 20. As a result there is no need for the lever 13. Here also the opera tion for forming the waste winding reserve winding and second waste bunch is essentially as described above with respect to the embodiment of FIGS. 1 to 4, with the exception that instead of the rod 9 being pivoted, here such rod is shifted transversely i.e. laterally towards and away from the lengthwise axis A of the thread package-support member 1.

Furthermore, and as best seen by referring to the em bodiment of FIG. 7, instead of using flat auxiliary thread guides 7 it is possible to provide auxiliary thread guides 24 which are suitably curved in the thread transport direction and can be pivotably arranged on the guide rod 9. Hence, as shown in full-lines in FIG. 7 the auxiliary thread guide 24 can possess a downwardly flexed portion 24' at the end opposite the thread guide edge 8. Also as shown at the right-hand portion of FIG.

7 in broken lines the free end 30 of the thread guide edge 8 of the auxiliary thread guide 24 can be downwardly flexed. As a matter of convenience in illustration the adjustment devices have been omitted, but may be like the devices and shown in FIGS. 1 4, the operation of forming the waste windings, reserve windings and second waste bunch again corresponding to that previously discussed.

Although the invention heretofore has been described by way of example with reference to winding apparatus for producing substantially cylindrical crosswound packages the teachings of this invention can also be applied to winding apparatus for producing conical cross-wound packages, for instance as shown in FIG. 7. In this case it is more suitable to arrange the guide rod 9 at least approximately parallel to the direction BR of the traversing motion of the traversing thread guide 4, rather than parallel to the axis A of the thread package-support member 1, as also shown in FIG. 7.

A major advantage of the winding apparatus of the invention resides in the fact that it permits the formation of a waste bunch and thread reserve windings at the beginning of the winding process, and a second waste bunch upon completion of the cross'wound package or also in case of premature interruption of the winding process, for instance due to disturbance. Furthermore, the duration of winding of waste thread or reserve thread and thus of the corresponding thread quantities can be varied within wide limits by adapting the pivoting speed of the auxiliary thread guide 7. Moreover, the central control device permits precise setting of the beginning and the end of the winding phase in the zone of the traversing thread guide at the same time for all winding locations or positions, and thus ensures for the production of packages of exactly the same weight at all winding positions.
